Abstract

From the preoperative partial nephrectomy planning perspective, it is essential to expose separately different kidney structures and to analyze their mutual topological relations. Only then, the identification of possible conflicts prior to surgical intervention can be facilitated. To enable this, we propose a segmentation frameworks for renal vascular tree, kidney and pelvicalyceal system from corresponding CT phases. In order to compensate for both patient position changes and volumetric changes related to respiratory activity, registration of different CT phases is required. It is performed by combining global rigid transform with multilevel and multiresolution B-spline registration. The research material consisted of fifteen patients that underwent CT scanning preceding kidney cancer surgery. Presented results using checkerboards and differential images prove the effectiveness of the proposed method. In addition, visualizations of the segmented structures (renal arteries, kidney, pelvicalyceal system) from registered CT phases are provided to exemplary demonstrate individual model for preoperative planning. This kind of solution meets the expectations of urological oncology in terms of facilitating planning the optimal surgical approach in partial nephrectomy. To the best of our knowledge, such a comprehensive strategy involving both the proposed segmentation frameworks and registration has not been introduced yet.
